GEOLOGY

Detailed explanation-1: -Answer: The material moved by erosion is sediment. Deposition occurs when the agents (wind or water) of erosion lay down sediment.

Detailed explanation-2: -Earth’s surface is constantly changed by erosion and deposition. Erosion breaks down Earth’s surface by carrying materials away from an area. Deposition builds up Earth’s surface when these materials are deposited in an area over time.

Detailed explanation-3: -Earth’s surface is constantly changing. Wind, water, and ice break down large rocks and move sediments on the surface. It usually takes years for weathering, erosion, and deposition to cause noticeable changes. Some events, though, change Earth’s surface much more quickly.

Detailed explanation-4: -Waves, wind, water, and ice shape and reshape the Earth’s land surface by eroding rock and solid in some areas and depositing them in other areas, sometimes in seasonal layers. Rock is composed of different combinations of minerals. Smaller rocks come from the breakage and weathering of bedrock and larger rocks.

Detailed explanation-5: -Deposition is the dropping, or depositing of sediments by water, wind, or ice. Deposition builds up new land on Earth’s surface, like a delta at the end of a river or the pile up of a sand dune in the desert. Shells on the beach are deposited by ocean waves.
